GE 531X111PSHARG3 Motor Field Control & Power Supply Board
Product Overview
The GE 531X111PSHARG3 is a Motor Field Control and Power Supply Board designed for GE’s EX2000 excitation system and part of the 531X replacement board series. As a G3 revision, it differs from prior versions by having external MOVs for AC lines and is engineered to power industrial drives and motor field electronics. Measuring 4 cm × 24 cm × 29.2 cm and weighing 0.58 kg, it generates three regulated DC power supplies critical for drive operation and integrates a pulse transformer to supply motor field circuitry.
It supports external exciters and includes three onboard relays for device control, plus three potentiometers for calibrating current feedbacks/circuits and five programmable jumpers for adjusting feedback/current signals. Installation requires trained personnel to follow GE’s guidelines to avoid damage; GE originally provided technical support, and it is compatible with GE-developed drives and exciters.

Key Features
Dual Functionality: Serves as both a power supply (5/15/24 VDC outputs) and motor field controller, integrating a pulse transformer to power motor field circuitry—eliminating the need for separate components.
G3 Revision Trait: AC line MOVs are external, a G3-specific design, optimizing onboard space and potentially simplifying maintenance of surge protection components.
Configurable Controls: Three potentiometers enable precise calibration of current feedbacks/circuits, while five programmable jumpers adjust feedback/current signals, adapting to diverse drive requirements.
Reliable Control Relays: Onboard K1 (RUN), K2 (MAX), and K3 (FAULT) relays provide clear, dedicated control for drive operational states, enhancing system safety and monitoring.
